loose on an intermediate drive shaft 39.. This drive shaft 32 is also equipped with pinions 33 enmeshed with the main gear Wheels 8.for driving the same. The loose sprocket 31 is a counterpart ot a worm wheel 34 also loose on said shaft 32 and rotates therewith. Keyed to said shaft 32 is a 'second worm wheel 35 by means of which said shaft is driven. The drive mechanism is otherwise substantially 'the same as in Patent No. 1,485,884 and briefly consists of a suitable motor 36, its shaft 3T, eountershaft 38, pinions 39-40 keyed to shaft 38, pinions 41-42 keyed to shaft 3T, sliding key 43 to interlock with either ot the p inions 39-40 or to disconnect entirely from both, and worms 44 on the shafts iT-H 38 for driving the Worm wheels 3fi-3. .5L hand lever, or a system thereof, 45 shifts il the sliding key 43, and in some instances automatic stop and reversing mechanism common to machines ot this general type may be provided.

The main gear wheels 8 are provided with projections having spaced tlanges 5l and 52 of different radial extent and adapted to engage and disengage a lateral projection 53 on each of the agitator carrying` arms lul, as in Patent No. 1,485,884 above mentioned.

' The main gear wheels are also provided with Cil 'a large projecting tooth 60 extending beyond the teeth thereof, and a similar tooth ('31 provided on the upper end of the teeth range. of the quandrant arms (3. It will be ohserved that for a distance from the tooth 61 there are no teeth 7 on the quadrant arms G and that this permits rotation of the main gear wheels 8 to lift the agitator carrying arms 14 a distance without elevating the fabric receptacle 4, but that as soon as the teeth and 61 become engaged, the teeth of the main gear Wheels 8 engage with those ot' the quadrant arms 6 and elevation of the fabric receptacle 4 begins.

In operation, assuming that the fabric receptacle is lowered in to the liquid tank and the mechanism has been operated to lower the agitator 22 into the said receptaele,-when the agitator is at the desired level according to the level of the dye liquor, the lowering mechanism is stopped and the agitator paddle operated. In this position, the teeth GO of the main gear wheels 8 will be somewhere between the Fig. 1 and Fig. 2 positions and the gear teeth of the gear wheels 8 out of mesh with the teeth 7 of the quadrant arms. lVhen it is desired to remove the goods, the hand lever 45 is shifted to stop the rotation of the agitator and to cause rotation of the main gear wheels in the saine manner as in said Patent No. 1,485,884, and as the gear wheels 8 rotate, the flanges 51 engaging with the projections 53 of the carrying arms 14, cause elevation of the agitator, As this elevation continues and at the point where the agitatorpaddle 22 would be working at the highest possible liquid level, the large tooth 60 of each gear wheel 8 comes into engageA ment with the large tooth 61 ot each quadrant arm 6, and as the elevation ot the agi tator carrying arms 14 and their associated mechanism continues, the teeth oll the main gear wheels 8 enter into mesh with the teeth 7 of the quadrant arms (i and the elevation of the fabric receptacle then begins. lYhen the agitator carrying arms 14 reach the vertical or substantially the vertical position. the eccentricity of the bearings has caused flanges 51 of each gear wheel 8 to clear the projections 53 of the carrying arms, and the gear wheels 8 are permitted to continue their rotation Without further action on the agitator carrying arms, but continuing their action upon the quadrant arms (5 until the fabric receptacle has been raised the desired degree, when by approjn'iate manipulation of the reversing mechanism, by sliding key 43 as in said patent, the main gear wheels 'S reverse their direction ot rotation. 'l`he flanges 52 of the gear wheels again encounter projections 53 ot the carrying arms 1l and return the agitator to a position within the tank, and at the same time gear wheels` S heing still emneshed with the teeth ot the quad rant arms ti, continue to return the, fabric receptacle to its position within the, tank. lVhen the fabric receptacle has been l'ully lowered into the tank, teeth T of the quadrant arms (5 leave the gear wheelsl 8 and the latter' continue rotation until such time as the ke)7 43 is shifted to stop rotation ot' the gear wheels 8. This shitting of the l-.ey 43 takes place when the agitator paddle L! has reached the point :recording to the level of the dye liquor at which it is desired the same should operate, and when that point is reached, by properly moving said key -l-). the agitator paddle may he rotated to eileet proper agitation of the dye liquor during` dyeing. It is to be pointed out that when the teeth 7 of the quadrant arms (3 leave those of the gear wheels 8, sudden dropping ot the quadrant arms 6 and the fabric receptacle is prevented by the large teeth titl-vol ha\VA ing become engaged, so that after the small teeth have acted in the lowering operation of the quadrant arms, the large teeth (tte-ot take up the work ot lowering, and atter tht` fabric receptacle is fully lowered. the mez-hanism may be then stopped to prevent turA ther lowering of the agitator, or the gear wheels 8 may be rotated farther to etl'eet turther lowering of the agitator, during which latter, the tooth (i0 of each gear wheel 8 merely moves away from the tooth til ol' the quadrant arms.

Having fully described the invent ion.y what is claimed as new and useful and desired to be secured by letters Patent is :m

1. The combination with a liquid tank, a

Sii

ltlti into and out of the same, a toothed quadrant arm for so moving the fabrie receptacle, an agitator movable into and out. of the fabric receptacle, a toothed member for so moving the agitator, the teeth ot said quadrant arm and membeiI enmeshing only when the fabric receptacle is ont et working' posiy tion, and Sui'iplemental teeth on ,said quart rant arm and member which interengag'e and effect enmeshing of said tiret mentioned teeth.

14. The combination with a liquid tank, a fabriereeeptaele mounted to swing into and out of said tank, and rotary agitator adapted to swing into and ont ot' the recept: ele; of a pivotally mounted agitator carrying arm havin@r a hollow tree portion formin g an a gitatoroearing and drive-gear casing.

l5. The combination with a liquid tank, of an agitator of less width than said tank pivotally mounted to swing t-ompletely into and ont or aiaid tank to vary its working depth, and means for actuating the agitator :it any point in its range ot sawing. movable with said agitator into Said tank..
